COMBINED BACKBAND BUCKLE AND TRACE SUPPORTING LOOP Filed oct. 2, 192e d' I z Inventar Patented Nov. 5, 1929 UNITED STATES WILLIAM LEROY BECTAN, F HALLS, TENNESSEE COMBINED BACKBAND BUCKLE TRACE-SUPPORTING LOOP Application iled October 2, 1928.

The present invention relates to improvements in buckles, and has reference more particularly to a back band buckle having associated therewith, means for supporting the trace in such a manner as to prevent the accidental disengagement of traces from the device.

A further object is to provide a combined back band buckle and trace supporting loop l0 that includes a sliding roller adapted to have binding engagement with the back band to positively secure the same against slipping.

A further object is to provide a device of the above mentioned character which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed. Other objects and advantages of the invention will become apparent from the following description when taken in connection with the accompanying drawing.

In the accompanying drawing wherein like reference characters indicate corresponding parts throughout the same:

backlband buckle and trace supporting loop embodying my invention.

Figure 2 is a longitudinal sectional view taken approximately on the line 2-2 of 0 Figure l showing the manner in which the back band is secured on the buckle, and

Figure 3 is a detail showing the construction of the back band engaging roller.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, thenumeral l designates generally the buckle, the same comprising a rectangular shaped plate 2, the ends of which are bent laterally to provide the parallel spaced flanges 3 and these flanges are formed with longitudinally extending alined slots 4 that are inclined, said slots extending inwardly toward the upper portion of the plate 2 as clearly suggested in Figure 2. The purpose of these slotted end portions or flanges will be presently described.

The rectangular shaped plate 2 is formed with the longitudinally extending parallel spaced upper and lower slots 5 and 6, respec- Figure l is a side elevation of the combined Serial No. 309,733.

tively, to accommodate the back band 7 in the manner as clearly shown in Figure 2.

A trace supporting loop 8 is arranged below the plate 2, and is furthermore disposed at right angles with respect to the plate. The free end portions of the loop S are disposed in diverging relation in an upward direction, and merge at their extremities with the lower edge of the plate 2 kadjacent the respective ends thereof, and these diverging arms are denoted by the reference character 9.

Upon referring to Figure 2 it will be observed that one side of the loop 8 lies in substantially the same vertical plane with the base plate 2 so that the back band 7 may eX- 65 tend downwardly along the spaced supporting loop 8 and the manner in which the loop supports the trace 10 is clearly indicated in Figure 2.

The invention further comprehends the provision of a backband engaging roller unit denoted generally by the reference character l1, and this unit comprises an elongated pin 12 that has its ends projecting through the alined slots 4. A sleeve 13 is mounted on the 75 pin 12 for disposition between the spaced slotted flanges 3 and suitable washers 14 are arranged on the outer end of the pin for engagement with the outer faces of the respecn tive flanges to prevent disengagement of the roller unit from the plate.

In Figure 3 of the drawings there is clearly illustrated the construction of the roller unit, and the manner in which the same is associated with one of the slotted flanges that eX- 85 tend laterally from the plate.

With an arrangement as hereinbefore described, it will be readily seen that the roller unit 11 will be held in clamping position relative to the back band 7 by the tension eX- 90 erted on the loop 8 by the trace 10. The binding action will be such as to cause no injury to the strap 10 as there are no teeth or other k gripping devices which mutilate or otherwise injure the material of the back band.

It will also be noted that with such an arrangement the adjustment of the back band and the buckle may be readily effected, and

also that the trace cannot accidentally become disengaged from the loop.

The simplicity of iny device enables the saine to be constructed at a very 10W cost, and the same will at all times be positive and etlicient in carrying out the purposes for Which it is designed.

Ihile I have shown the preferred embodiment of my invention, it is to be understood that minor changes in the size, shape and -arrangement of parts may be resorted to without departing from the spirit of the invention and the scope lofthe appended claim.

Having thus described the invention, what I claim as new and desire 'to secure'by Letters Patent is:

In a device of the class described comprising a plate formed with upper and lower slots to accommodate a back band, slotted anges extending laterally from the ends of the plate,

Y the slots in the ianges being arranged at an acute angle with respect to the plate, a back band engaging roller unit operable through the slots in the rear flanges, for the purpose of frictionally holding the back :band in adjusted position, and a trace supporting` loop carried by the. lower edge portion of the plate, said loop beingdisposed at right angles with respect to the plate.

In testimony whereof lI ax iny signature.

WILLIAM L. BECTAN.
